This invention Arelates to machines for transferring decalcomanla stamps to cloth or fabric and is intended to provide certainimprovements in the type of machine set forth inmy pending application forUnitedV States priate tape feeding' mechanism coordinated Withfthe revolutioneofthe drum and lWith a revolving presser cooperatively arranged inoppositionvto the;y platen so thatat regular intervals on` the L'cloth thejA design kontrade-` mark, embodied in eachV stamp carried by the stamp tape, i'sfhot pressed near 'the edge of the fabric travelling over the drum. 1 d

Inl practice. itis found thatthe decal comania. stamps', constituting the designy or trademark being pressed on the clothare not always exactly evenlysp'aced on: the Hcarrier tape ony which they are placed for use. This may be dueto irregularitiesin spacing vof the 'stamps on the carrier tape, lor lit may be due to changes of length of the tape ldue to varyingatmospherie conditions. l In the machine Vof .my earlier .application itwvas V'found that when, *lowing to either of these y causes, some of the transfer stamps yfailed n 5 `to properly register With ythe* revolving presser only7 a partial impression or perhaps no impression at all of thestainpkwould be` inadeonthe cloth, yand it became necessary to vstop the machine to readjust thetape and l I p y construction of this dierential stripper actu- 'Fig 7 is ai rear en'delevation ofthe the feeding mechanism.

Y. f As ythe generale construction and arrange ment of this machine is similar to that described in my aforesaid earlier application, I will herein only briefly describe the features common to both applications, leaving for specific description the new construction and arrangements which constitute the present Iimprovements.

As in my former application the machine comprises, generally speaking, a revoluble cylinder or drum A rotatably supported atits oppositeends-by stub shafts 1 and -1,-tlie peripheral shell being truncated or cut away to expose a flatheated .platenor bed 2 inline with a preliminary heating plate 3, over which the carrier tape that is providedy at short intervals with transfer stamps of the usual gumrny character, yis drawn to bring successive st amps to the middle portion of the platen 2 underneath the cloth and against which the cloth is pressed by the revolving presser foot 8 pivotally vmounted on the rcvoluble arm 7 secured to the overhead coun tershaft, that is driven in coordination with the drum by means of the gear intermeshing with the gea-r 4 secured to the outer end of the stub shaft 1, which is located at what may be termed theaotuating end of the machine or drum.

` The tape feed, of course, must be so coordinated with the revolution of the drum that at .each revolution of the drum, at the point where the platen 2 meets and is pressed by the presser member 8, each successive transfer stamp will bepositioned in registry with both pressing elementsy so as to impress or` transfer fthe stamp to the superimposed portion of the cloth during the brief period that the presser and the platen revolve in pressing relationship to each other. It must be borne in mind that the cloth travels circumferentially around the drum with one edge portion between the paths of revolution of the two presser elements, while the tape carried inside the drum is fed axially or lengthwise ofthe drum, rthat is .at substantially right angles to the travel ofthe cloth. Now, no materhow accurately the tape feeding means may be adjusted if, as frequently happens, the transfer stamps carried bythe tape are not uniformly spaced apart, it may .happen thatthe stamp, insteadfof coming to restafter its yintermittent feeding motion exactly in registry with t thel revolving presser foot, may be .partially oryvholly offset lengthwiseof Ithe drum with relation tothe'presser and therefore will only beepaltly impressed upon the. fabric, orvmay not be impressed thereon at all. y

.As the operator of the machine iswatching `the lclothes it passes over the drum, he can readilynotice any, tendency of the stamp impressions, tobeeome koffset n so as to be impressedtoonear the edgelof thefabridor not to be transferred ,at all by reason offailure to register at all with the presser member.

Theref0re,l have herein made .provision for rectifying this fault by providing mechanism which can be operated by the attendant when the machine is running to advance the tape so as to secure proper positioning or registry of the successive stamps with the correct pressing position as often as such correction may be needed.r

As in my earlier application the stamp carrying tape is wound in a coil or spool and placed on a revoluble reelr 10 mounted inside therdrumf-somewhat toward the middle of the drum. As shown in Fig. 2, the tape as uncoiling froxn-therevoluble reel passes over a transverse guide bar 11, thence around a stripper comprising a transverse roller parallel to the axis of the tape reel mounted in parallel arms 13 secured to a rock shaft 14, the actuation of which will be presently described. From the stripper the tape a: passes over and around feed roll and coacting idler feed roll 31, whence it is drawn across the hot plates 3 and 2 by a pair of corrugated draft rolls 50, which deliver the waste end of the tape, whose stamps have been impressed'on the` fabric, into a waste receptacle formed in the adjacent end of the drum from which it may be removed from time to4 time, through a hand hole, rby the operator. The

ydraft rolls are driven as in my formerapyplication by an actuating gearl mountedon thefend head of the drum andy rotating about a transverse axis by reason of its toothed engagement with a helical cam 52 encircling the cylindrical box 53, in which the end shaft 1 of the drum is mounted. This worm cam 52 is so proportioned that as the gear 51 is carried one revolution around it the gear is moved one tooth with a. pause ormomentary dwell at the middle part of the revolution caused by making this portion ofthe worm cam flat or withoutoblique inclinatiom as shown at 52". By a suitable ytrain of mechanism embracing intermeshingpinions 54, 54a, and a'frictionally connected sprocket 55, the yshort sprocket chain 56 having a frictional drive connection with an overhead countershaft 57 carrying a pinion 58 intermeshingwith la pinion 59 on the end of one ofthe intermeshing draft rollers 50, vthese draft -rollers'are given a rotation sufficient to lreepthe advanced end of the tape drawn taut over the pressing bed 2. The fric- .tional connections in this train of gearing just described are for the purpose of allowing the draft rollers to run at ai higher surface Speed than isdesired for the travel of the tape without breaking the tape, as would happen in such ycase ifthe driving train exerted a positive driveonthese draft rolls. This insures 'preventing any slack of the tape, while keeping it stretches out flat in proper position for the transfer operation. f Y

Instead of driving the tapedeliveringor feeding mechanism that regulates or controls the rate of deliveryof the tape to transfer position on the platen through the same train of :mechanism that drives therolls inf-my 'earlierapplicatiom I herein provide ineans actuatedA independently of the draft roll Inside of the end frame Whichcarries vthe fixed tubular box or housing`53 on which f the Aworm cain 52 is mounted and secured, I mount a rotatablyadjustable spur gear 32 that is compounded withfa sprocket wheel 33conneoted by a sprocket chain 33a' with a small y ratchet and pawl connection from the sprocket 43, it will befobviousthat if the sprocket 'pinion 34finounted on a short shaft that -isprovided with a vhand wheel 35,v by

which the operator can adjust the spur gear 32circumferentially. `Onthis shaft *is se-v curedr aV perforated dial disk36, whose? dial holes may be brought in'registry withf'a stop pin `37 carriedby theV frame B"so that the adjusting sprocket 34inay be set to any desired rotative positiongandreleasably locked there'against accidental displacement.V

'lisis It will be understood that this spur gear is normallyl stationary, 'but that 'itA causes rotation'of a pinion 37 a mounted on the adjacent end of a feed'actnatingor transmission shaft 38 extending longitudinallyof the drum and having' driving connection with the shaft of the feed'roll`30 througha worin and gearconnection at 39.` ExceptV for the driving ymeans just described, the feed or delivery rolls 30, 31 are constructed and arranged as described in fdetail infiny aforesaid pending, application. x

On the feed' roll'shaft 40 is secured a sprocket 4l, that transmitsthe rotationof f* the feed roll toa counter-shaftV 42'1by means -ofa sprocket wheel 43, which is secured 'toi a tubular shaftf44 Vsurrounding theshaft 42;

-ifisshown in Figs.A` 6 and 8, rotary motion transmitted to theftubular shaft orsleeve 44` K n y,through the speed accelerating pinions-47a,

by the sprocket Vwheel 43 is norinallytrans Vinitte'dto the inner shaft 42 by means of pivisisk lVoted `pawls 45" arranged in pairs on the side of the sprocket` wheel 43, which pawls 'normall-y engage a ratchet wheel 46 thatis secured to the inner shaft 42.

On the opposite end of the shaft- 42 is a :sprocket wheel VOthat transmits rotary mortion froin this shaft tothe revoluble reel `means of a sprocket Vchain 6l and sprocket Wheel 62 on the end ofthe reel shaft,so that through ythe normal driving4 connection the il tir Y j it. Y n* y roel isslowlyrotated to release frointhe coil Loi?. spool tape that is ktaken up bythe stripper i 12,11'3. To avoid an overdelive'ry of tape from the reelto the stripper, this normal rotation is somewhat sl-owerfthanthe Aamount of tape delivered by the feedregulatingrolls rectiontoward the reel'against they tensionof (thev` contractile Yspring 46a, which `ynormally tends, throuoh thelinlr and lever connections 45,116, to pull the stripper yieldingly away "from the reel to' draw or strip'oif from the reel predetermined lengths of tape.

Therefore, to compensate for the relatively lslower rotation of the reel in delivering tape ,7

to the stripper provisionis made for speeding up orY accelerating the unwinding rotationof the reel, 4as often as itinay be'needed.

This accelerated action is acooinplishedby an alternating drive connection between ,the sleeve or tubular shaft l44 and the inner shaft which will now be described.' ASince the shaft 42 is driven through vthe shaft v42 is accelerated its ratchet wheel 46 canreadily overrun Ythepawls 45Awithout inf terferingjwithj the normal rotation of ithesprocket 43. Referring more particularly to Fiss; G and 7, there isjshown.loosely,mountg ed on the sleeve 44 a ratchet wheel 47 :alongside ofa pinion 48, thaty is lreyedto the sleeve 44 to revolve in unisontherewith. The pinion48 nieshes with-'a pinion 47a that is secured to a short spindle or shaft`47b rotatablymountf ed inthe ratchet wheel-47 near its periphery position to engage the teethof the ratchetV 47' ksofas to hold the ratchet against rotation. So long astlie ratchet is free to revolve Withthe sleeve 44 and the pinion 48 thatl is splinedto-` saidsleeve, 'therewillbe no iiidepenoent ro'- tation of the planetary pinions 47 and 47,

so that this wh'oleplanetary inoveinent,fcom

prisingjthe pinion 48, the pinions 47 a, aind-47 C',

siin l revolveswiththe sleeve-44.'V When tive rotation of the pinion 48, 'working 47"', roperates to Vrotate the shaft 42 considerably faster than the sleeve 44 rotates.

this accelerationof rotationis recuiredonly however, the ratchet47 is engaged and held n by .its pawl 47dv against rotation, then the relan occasionally and shouldoeaseas soon as the' l i stripper has returned to rearward or mair-K4 iinuin i drawing "off position, Il provide a l knock-caff `for throwing vthe pawl47d out of engagement with the ratchet V47. f 'This lrnoolr-oiffnieinhercoinpriscs a polygonal cam 49 fastoii sleeve 44, whose high portions or corners, when engaging i a 1r0llerl47e carried by, andV laterally offset Withielatfon to, the

pawl47l servesto swing the gaivl out Vofengageinent with-the ratchet47 rwhere it is latched against re-engagenienty by ineansj of the trip latchl'a, whichis normally thrown into latching position by the'vcontractile springl?.

Theiratchetholding pawl 47d is released frointhe latchl'@ whenever the stripper advances far enough forwardly toward the reel l to advance the link 17`far enough' to *release*y Y this latchla, therebeing lprovided a kslotiat l `fili 17c to give a certain amount of lost motion between the link 17 and the latch member 17 a. Inthis advanced position of the stripper with the link 17 thrusting against the latch 17a, the latch 17 is held in released position against its return spring 17b until the stripper` has moved rearwardly drawing ofi' the tape that has been simultaneously released or uncoiled bythe accelerated rotation of the reel already described.

It will therefore be seen that adequate provision is made for preventing an excess unwinding of the reel by giving it an unwind- Ving motion too slow to supply the requirements of the `feed delivering rolls, while at the same time provision is made for accelerating the unwinding of the tape from the reel as often as the stripper approaches its forward position where all the slack taken up yhas been paid out. To summarize, the cloth engaging drum rotates continuously while engaged by the cloth travelling around its periphery, while Vthe tape feeding means acts intermittently to deliver properly regulated lengths of tape to the transfer point or position, the delivery of thistape being controlled by the feed regulating or delivering rolls, which are properly suppliedwith the stamp carrying tape under light tension from the stripper through the agency of the differential speed reel rotating mechanism. The used end of the tape beyond the transfer point is kept taut by the pull of thev draft rolls which, however, are drivenby an actuating mechanism that is independent of the tape delivering mechanism, thus yallowing the tape delivery to be accelerated by the operator ywhile the machine is running through the medium of the adjusting wheel 35 interconnected with the normally stationary but rotatably adjustable spur gear 32.

It will be seen that while the unwinding of the tape reel is intermittently and automatically accelerated, the feed rolls deliver a uniform length of tape kaccording to their adjustment, unless they are accelerated by the attendant through the adjustment or manual advancement of the actuating spur gear in yorder to effect proper positioning or registry of the successive transfer stamps with the Atransferring or pressing members.' Therefore, by merely watching the line of successive st-amp impressions nearthe edge of the cloth after the cloth leaves the drum the operator canfalways maintain proper stamp positioning above the platen without even slowing down the machine'.
